| 31 | | === For SQLite === |
| 32 | | |
| 33 | | * [http://www.sqlite.org/ SQLite], version 3.3.4 and above preferred. |
| 34 | | * If not using Python-2.5: [http://pysqlite.org/ PySQLite], version 1.x (for SQLite 2.x) or version 2.x (for SQLite 3.x), version 2.3.2 preferred. For details see PySqlite |

| | 38 | ==== For SQLite ==== |
| | 39 | |
| | 40 | If you're using Python 2.5 or 2.6, you already have everything you need. |
| | 41 | |
| | 42 | If you're using Python 2.3 or 2.4 and need pysqlite, you can download from |
| | 43 | [http://code.google.com/p/pysqlite/downloads/list google code] the Windows |
| | 44 | installers or the tar.gz archive for building from source: |
| | 45 | {{{ |
| | 46 | $ tar xvfz <version>.tar.gz |
| | 47 | $ cd <version> |
| | 48 | $ python setup.py build_static install |
| | 49 | }}} |
| | 50 | |
| | 51 | That way, the latest SQLite version will be downloaded and built into the |
| | 52 | bindings. |
| | 53 | |
| | 54 | If you're still using SQLite 2.x, you'll need pysqlite 1.0.x, although this |
| | 55 | package is not easy to find anymore. For SQLite 3.x, try not to use |
| | 56 | pysqlite 1.1.x, which has been deprecated in favor of pysqlite 2.x. |
| | 57 | |
| | 58 | See additional information in [trac:PySqlite PySqlite]. |
| | 59 | |
| | 60 | ==== For PostgreSQL ==== |
| 43 | | * [http://initd.org/projects/psycopg2 psycopg2] or [http://pypgsql.sourceforge.net/ pyPgSQL] |
| 44 | | |
| 45 | | === For MySQL === |
| 46 | | |
| 47 | | '''Warning''': MySQL support is currently ''still'' experimental. That means it works for some people, but several issues remain, in particular regarding the use of unicode and the key length in the repository cache. See MySqlDb for more detailed informations. |
| 48 | | |
| 49 | | * [http://mysql.com/ MySQL], version 4.1 or later |
| 50 | | * [http://sf.net/projects/mysql-python MySQL-python], version 1.2.1 or later |
| 51 | | |
| 52 | | === Optional Requirements === |
| | 63 | * [http://initd.org/projects/psycopg2 psycopg2] |
| | 64 | * See [trac:wiki:DatabaseBackend#Postgresql DatabaseBackend] |
| | 65 | |
| | 66 | '''Warning''': PostgreSQL 8.3 uses a strict type checking mechanism. To use Trac with the 8.3 Version of PostgreSQL, you will need [http://trac.edgewall.org/changeset/6512 trac-0.11] or later. |
| | 67 | |
| | 68 | ==== For MySQL ==== |
| | 69 | |
| | 70 | * [http://mysql.com/ MySQL], version 4.1 or later ([http://askmonty.org/wiki/index.php/MariaDB MariaDB] might work as well) |
| | 71 | * [http://sf.net/projects/mysql-python MySQLdb], version 1.2.1 or later |
| | 72 | |
| | 73 | See [trac:MySqlDb MySqlDb] for more detailed information. |
| | 74 | It is ''very'' important to read carefully that page before creating the database. |
| | 75 | |
| | 76 | == Optional Requirements == |
| 56 | | '''Please note:''' if using Subversion, Trac must be installed on the '''same machine'''. Remote repositories are currently not supported |
| 57 | | |
| 58 | | * [http://subversion.tigris.org/ Subversion], version >= 1.0. (versions recommended: 1.2.4, 1.3.2 or 1.4.2) and the '''''corresponding''''' Python bindings. For troubleshooting, check TracSubversion |
| | 80 | '''Please note:''' if using Subversion, Trac must be installed on the '''same machine'''. Remote repositories are currently not supported (although Windows UNC paths such as {{{\\machine_name\path\to\svn}}} do work). |
| | 81 | |
| | 82 | * [http://subversion.tigris.org/ Subversion], version >= 1.0. (versions recommended: 1.2.4, 1.3.2 or 1.4.2) and the '''''corresponding''''' Python bindings. For troubleshooting, check [trac:TracSubversion TracSubversion] |
| 69 | | * [http://httpd.apache.org/ Apache] with [http://code.google.com/p/modwsgi/ mod_wsgi] (see [wiki:TracModWSGI]) |
| 70 | | * While mod_wsgi is very new and somewhat experimental, this should work with Apache 1.3, 2.0 or 2.2 and promises to deliver more performance than using mod_python. |
| 71 | | |
| 72 | | For those stuck with Apache 1.3, it is also possible to get Trac working with [http://www.modpython.org/ mod_python 2.7] (see [wiki:TracModPython2.7 TracModPython2.7]). This guide hasn't been updated since 0.84, so it may or may not work. |
| | 97 | |
| | 98 | For those stuck with Apache 1.3, it is also possible to get Trac working with [http://www.modpython.org/ mod_python 2.7] (see [trac:wiki:TracModPython2.7 TracModPython2.7]). This guide hasn't been updated since 0.84, so it may or may not work. |
| 80 | | '''Attention''': The various available versions of these dependencies are not necessarily interchangable, so please pay attention to the version numbers above. If you are having trouble getting Trac to work please double-check all the dependencies before asking for help on the MailingList or IrcChannel. |
| 81 | | |
| 82 | | Please refer to the documentation of these packages to find out how they are best installed. In addition, most of the [wiki:TracInstallPlatforms platform-specific instructions] also describe the installation of the dependencies. Keep in mind however that the information there ''probably concern older versions of Trac than the one you're installing'' (there are even some pages that are still talking about Trac 0.8!). |

| 145 | | Trac provides three options for connecting to a web server: [wiki:TracCgi CGI], [wiki:TracFastCgi FastCGI] and [wiki:TracModPython mod_python]. For decent performance, it is recommended that you use either FastCGI or mod_python. |
| 146 | | |
| 147 | | If you're not afraid of running development code, you can also try running Trac on [wiki:TracModWSGI mod_wsgi]. This should deliver even better performance than mod_python, but the module is not considered stable just yet. |
| | 181 | Trac provides three options for connecting to a "real" web server: [wiki:TracCgi CGI], [wiki:TracFastCgi FastCGI] and [wiki:TracModPython mod_python]. For decent performance, it is recommended that you use either FastCGI or mod_python. |
| | 182 | |
| | 183 | If you're not afraid of running newer code, you can also try running Trac on [wiki:TracModWSGI mod_wsgi]. This should deliver even better performance than mod_python, but the module isn't as extensively tested as mod_python. |
| | 184 | |
| | 185 | Trac also supports [trac:TracOnWindowsIisAjp AJP] which may be your choice if you want to connect to IIS. |
| | 186 | |
| | 187 | ==== Generating the Trac cgi-bin directory ==== |
| | 188 | |
| | 189 | In order for Trac to function properly with FastCGI or mod_python, you need to have a trac.cgi file. This is an executable which loads the appropriate Python code. It can be generated using the `deploy` option of [wiki:TracAdmin trac-admin]. |
| | 190 | |
| | 191 | There is, however, a bit of a chicken-and-egg problem. The [wiki:TracAdmin trac-admin] command requires an existing environment to function, but complains if the deploy directory already exists. This is a problem, because environments are often stored in a subdirectory of the deploy. The solution is to do something like this: |
| | 192 | {{{ |
| | 193 | mkdir -p /usr/share/trac/projects/my-project |
| | 194 | trac-admin /usr/share/trac/projects/my-project initenv |
| | 195 | trac-admin /usr/share/trac/projects/my-project deploy /tmp/deploy |
| | 196 | mv /tmp/deploy/* /usr/share/trac |
| | 197 | }}} |
| | 198 | |
| | 199 | ==== Setting up the Plugin Cache ==== |
| | 200 | |
| | 201 | Some Python plugins need to be extracted to a cache directory. By default the cache resides in the home directory of the current user. When running Trac on a Web Server as a dedicated user (which is highly recommended) who has no home directory, this might prevent the plugins from starting. To override the cache location you can set the PYTHON_EGG_CACHE environment variable. Refer to your server documentation for detailed instructions. |
| | 211 | == Automatic reference to the SVN changesets in Trac tickets == |
| | 212 | |
| | 213 | You can configure SVN to automatically add a reference to the changeset into the ticket comments, whenever files are committed to the repository. The description of the commit needs to contain one of the following formulas: |
| | 214 | * '''Refs #123''' - to reference this changeset in #123 ticket |
| | 215 | * '''Fixes #123''' - to reference this changeset and close #123 ticket with the default status ''fixed'' |
| | 216 | |
| | 217 | All you have to do is to edit the ''post-commit'' hook in your SVN repository and make it execute ''trac-post-commit-hook'' coming with Trac. |
| | 218 | |
| | 219 | If you are editing the ''post-commit'' hook for the first time you need to navigate to your SVN repository's hooks subfolder and rename existing there ''post-commit'' template: |
| | 220 | |
| | 221 | {{{ |
| | 222 | $ cd /path/to/svn/repository/hooks |
| | 223 | $ mv post-commit.tmpl post-commit |
| | 224 | $ chmod 755 post-commit |
| | 225 | }}} |
| | 226 | |
| | 227 | Next open it in any text editor and add a line with path to the Trac environment connected with this SVN repository and another line executing the ''trac-post-commit-hook'' script: |
| | 228 | |
| | 229 | {{{ |
| | 230 | REPOS="$1" |
| | 231 | REV="$2" |
| | 232 | TRAC_ENV="/path/to/your/trac/project" |
| | 233 | |
| | 234 | /usr/bin/python /usr/local/bin/trac-post-commit-hook -p "$TRAC_ENV" -r "$REV" |
| | 235 | }}} |
| | 236 | |
| | 237 | Make sure that ''trac-post-commit-hook'' exists in above path with execution permissions for the same user which SVN is running from. This script can be found in contrib subfolder of your Trac distribution and the latest version can be always downloaded from [trac:source:branches/0.11-stable/contrib/trac-post-commit-hook branches/0.11-stable/contrib/trac-post-commit-hook]. |
